BALL-BEARING.

SPECIFICATION forming part of Letters Patent N o. 626,274, dated June G, 1899.

Application tiled December 17, 1898. Serial No. 699,597. (No model.)

To all 71171/0771, it nifl/ 7] concern:

Be it known that I, MATHIEU FQIDART, a citizen of the Kingdom ot' Belgium, residing at Brussels, Belgium, have invented certain q new and useful Improvements in Ball-Bearings, of which the following is a specification.

My invention relates to ball-bearings for shafts, axles, and the like and especially for heavy-vehicle bearings.

The objectof the invention is to provide a ball-bearing in which any number of rows of balls may be used, and each row ot balls will be held from lat-eral movement without it being necessary to provide the usual circular or r otherwise-shaped ball-races.

The invention consists in certain details of construction hereinafter set forth, and particularly pointed out in the claims.

In order that the invention may be the more zo properly and readily understood and carried into practical effect, I have illustrated the same in the accompanying explanatory drawings, in which-- Figure lis avertical longitudinal sectional view of a ball-bearin g constructed in accordance with my invention. Fig. 2 is a cross-section on X Y of Fig. 1. Fig. 3 shows the end tightening-plate. Fig. et is a vertical longitudinal sectional view of a ball-bearing having intermediary balls, and Fig. 5 is a crosssection on V Z of Fig. 4.

In the drawings like letters refer to like parts throughout all the gures.

The improvements principally consist of a smooth sleeve A, loosely mounted on the axlejournal C and provided at one end with a suitable flange a, the other end of said sleeve being cut away at determinate points to re-. ceive radial lugs o, provided on plate B, Fig.

4o 3. Said plate is 4applied against the end of journal C and fastened thereon with a tongueand-grooved connection by a suitable extension b', projectingfrom said plate and extending into a corresponding recess in journal C.

A head-bolt D under the action of a coiled spring d serves to hold said plate B in place on the end of journal C. The shank of said bolt and said coiled spring are lodged in a suitable recess e, provided in the center of 5o an externally-threaded cap E, screwed in the internally-threaded end of journal-boxF and abutting against the outer end of a second Vor lateral movements of a car or other vehicle. Vith the aforegoing construction and arrangement the thrust is taken up by the coiled spring of bolt D and does not at all affeet plate B.

i The slight tendency of cap E to be inscrewed may be efficiently overcome by means of a screw extending through oil-channel L.

On sleeve A are loosely mounted suitable rings f, and between the successive rings are arranged series of balls g. The innermost ring f rests against the aforesaid flange a., and the outermost ring f, as well as the intermediary rings, are maintained by the end of lugs b on plate B.

In Figs. 4 and 5 of the accompanying drawings I have illustrated a similar ball-bearing, except that the main balls g are held out of contact with one another by smaller intermediary balls g.

The fore part of the journal-box has an oil passage or conduit h extending through the wall of said box and the cap E and through which oil or any suitable lubricant may be introduced into said box, where it occupies the bottoni part, to maintain the balls in a lubricated state during the movement of the vehicle.

I have found that the insertion of rings, such as f, is much more advantageous than the usual grooves or circular ball-races, said rings preventing the balls very efficiently from deviating from their circumferential way. Furthermore, the intermediary balls inserted between the main balls serve to remove any friction between the latter, and therefore reduce the friction of the system to a minimum.

The various parts of Vmy invention being` ICO liable to be modied as to the construction and arrangement thereof without departing from the spirit and scope of the invention, I Wish it to be understood that' I do not confine myself to the precise construction and ar# rangement of the parts as shown in the accompanying drawingsr so long as the peculiar features of my invention be retained.

Having fullyT described my invention, what I claim, and desire to secure by Letters Pat-- ent, is

l. In aball-bearing, the combination with a journal and a sleeve Whichis mounted thereon and adapted to receive the antifrictionballs externally, of a series of antifrictionballs, an inclosing box or easing, a disk plate tting against one end of the said sleeve and journal, and independent spring actuated means for holding the said plate in said position by pressure, substantially as set forth.

2. In combination with the journal C re-f cessed at its end, the plate B havinga part b" which iits into the said recess, a spring-bolt D bearing against the outer face of the said plate, a sleeve iitting on the said journal, a

,box inelosing the said parts and a series of
